Pretty girls challenge beauty perception with ugly face shots

The ongoing "Pretty Girl, Ugly Face Shot" photo trend serves up a constant stream of hilarious side-by-side shots of pretty girls making hideous faces.

From grumpy smiles to double chins and crossed eyes, these women don't hesitate to show their inner "ugly duckling", as posted on China Forum Daily.

Even more, they seem to be making a statement about loving yourself as you are, caring less about others' opinions and having some fun.
